Since recently osmo-pcu arms the X2002 in a more fitting place (later,
when paging.cnf is received from osmo-bts over PCUIF).
Since we use same X2002 value in TTCN3 to wait for the timer to trigger,
in the past it was always fine (the X2002 at osmo-pcu always already had
triggered before the one in ttcn3 after receiving the ImmAss).
However, now the timer is roughly set at the same time in both places (ttcn3 and
osmo-pcu) and hence there may be race conditions where we request a
DL data block before the X2002 triggered at osmo-pcu, in which case we
receive a DL dummy block because the TBF is not yet in the FLOW state.

There also exists UL equivalent of this message, for which I am
planning to add a template. Let's clarify direction in the name.

New versions of osmo-pcu will validate the Pkt Resource Request is sent
on the correct FN, so we must send first UL block exactly when
requested.

This test currently fails to pass in master osmo-pcu (and latest) due to
T3169 not being implemented exactly as per specs (due to limitations in
detecting lost UL blocks with assigned USF).

Triggers osmo-pcu assert in nacc_fsm.c due to scheduler not checking if
tbf has TFI assigned before deciding to transmit NACC related messages.

Notification messages are ignored once the NACC procedure is already

Fixes:
warning: Inadequate restriction on the referenced template parameter
`chreq_desc', this may cause a dynamic test case error at runtime

This is only a step towards a major set of changes.
This specific commit changes internal implementation of functions to stay
compatible with existing tests.
Later on, changes will be modified to use the new altsteps directly.

Allow ignoring for received dumy packets while waiting for a Pkt Ass on
PACCH. This fixes some tests failing sometimes due to race condition
where rlcmac packet is requested too quicky, after the PCU has received
the BSSGP packet we sent to it.
The function is splitted into an internal altestep + a wrap function
which is compatible with tests already using it.

LLC UI dummy frames are only to be sent alone in order to delay TBF
termination. Until recently (osmo-pcu.git
Ifae1a7b2b3dfad8df19585063088ba0df2749c8f), osmo-pcu was sending LLC UI
dummy frames instead of padding at RLCMAC layer, which made no sense.

ARFCNs are allocated sequentially, so that conversion between
arfcn<->trx_nr is easily done.
Some helper functions are introduced to be able to submit and expect
messages on a given TRX+TS, which is required for setups with several
TRX and PDCH-enabled TS different than the default. These new APIs
will be used in PCU_Tests.ttcn in subsequent patches.

In TTCN-3, array assumes a fixed number of elements. A 'record of'
type is more like a 'list' in Python, so let's call it this way.

This change will facilitate adding test cases for multi-slot TBF
allocation across several TS and/or TRX instances of a BTS.

Immediate Assignment is sent on AGCH/PCH, while on PACCH we have
Packet Uplink/Downlink Assignment instead (see 11.2.29, 11.2.7).
